Hello,
I reading an article and i can't understand well about scaling factor.
Could you give me definition and example about scaling factor?
How can embed one matrix to other matrix with scaling factor?
Thanks

A = (out - B*s) / (1-s)

Thank you for your reply,
yes, but when watermark image in the cover image(A and B) , we lost A and B in watermark image.
We just s and out . we don't have A or B.
We don't have B to calculate A. or A to calculate B.We just s and out

The paper is vague on that. It also says it is "embedded on the singular values of cover image", but there are only 2*min(W+H) non-zero values in the "singular values" matrix. So I don't know how that works.
